2 cards from this section. Quick, good the night before a test.
What are the three terminals of a BJT?
Think of the structure and name the parts you see.
Define forward bias in a BJT.
Consider which direction you want the current to flow.
What is the primary current flow direction in the BJT when the base-emitter junction is forward biased?
Think about where charge carriers originate.
True or False: The base-collector junction in a BJT is typically forward biased during normal operation.
Consider what conditions are needed for current to flow.
Analyze a BJT circuit where the base current is 20 µA, and the current gain (β) is 100. What is the expected collector current?
Remember the relation of current gain in BJTs.
Given a BJT with a V_BE of 0.7V and a collector saturation current (I_S) of 10 nA, calculate the collector current at room temperature (approximately 25°C).
Still using the diode equation, keep an eye on exponential growth!
